Welcome New Department of Computer Science Faculty!

Aug. 9, 2019

The Department of Computer Science welcomes its newest faculty members. Read below to get to know the new faculty. 

Meet Kwang-Sung Jun

“I am currently a postdoc with Francesco Orabona at Boston University. In Fall 2019, I will join the Department of Computer Science at the University of Arizona as an assistant professor. I do machine learning. My research focuses on sequential decision-making in feedback loops (i.e., the multi-armed bandit problem). I also work on online optimization and some active learning problems. In the past, I had fun with a few collaborations with psychologists. I was previously a postdoc with Robert Nowak, Rebecca Willett, and Stephen Wright at UW-Madison Wisconsin Institute for Discovery under optimization theme. I received my PhD in 2015 at University of Wisconsin-Madison, advised by Xiaojin (Jerry) Zhu. I obtained a B.S. in computer science with a minor in mathematics from School of Computing, Soongsil University, South Korea.”

Meet Chicheng Zhang

Chicheng Zhang is an assistant professor in the Department of Computer Science at the University of Arizona. From September 2018 to June 2019, he was a postdoctoral researcher at the machine learning group of Microsoft Research New York City. He received a Bachelor degree from Peking University in 2012 and a PhD in Computer Science from UC San Diego in 2017. Chicheng has broad research interests in machine learning and learning theory, including but not limited to topics such as active learning, contextual bandits, unsupervised learning and confidence-rated prediction. His main research interests lie in the design and analysis of efficient and robust interactive learning algorithms.


Meet Jason Pacheco

Jason Pacheco is an assistant professor in the Department of Computer Science. Jason’s research interests are in statistical machine learning, probabilistic graphical models, approximate inference algorithms, and information-theoretic decision making. Prior to joining the University of Arizona, Jason was a postdoctoral associate at MIT in the Computer Science and Artificial Intelligence Laboratory (CSAIL) with John Fisher III. Jason completed his PhD work at Brown University with Erik Sudderth.
